In adjustable gastric banding (the LAP-BAND® System), the stomach is encircled with an inflatable band that provides restriction of food intake. This allows only a small portion of the stomach to be used for holding food. A person feels “full” on much less food. Weight loss achieved is less than with gastric bypass since no intestine is bypassed and there is no malabsorption. This procedure is superior to gastroplasty (see below), as it is adjustable to optimize weight loss. Absence of stapling during this procedure makes it the least invasive and lowest risk.
The upper stomach is stapled in a vertical direction with a pre-measured plastic band separating the upper and lower stomach. The band prevents the stomach from stretching at this point. We use specific criteria pertaining to an individual’s health and potential risks when deciding who should have a gastroplasty and who should have a gastric bypass. Most patients will qualify for laparoscopic gastric bypass surgery.
